Featuring unique phase transformation toughening property, these zirconium oxide grinding balls resist cracking and chipping under high-speed impact and cyclic friction, maintaining complete spherical shape and stable grinding efficiency for a long time. With ultra-low wear rate, they produce minimal fine debris during operation, effectively avoiding material pollution and ensuring high purity of finished products. In addition, the media boasts excellent chemical inertness, resisting corrosion from most acids and alkalis, and stable performance in high-temperature and high-viscosity working environments. Its high density greatly improves grinding collision energy, realizing faster ultra-fine pulverization and uniform particle size distribution to enhance production efficiency.
These durable grinding media are widely applicable for ultra-fine grinding and dispersion in multiple precision industries. They are ideal for electronic ceramics, magnetic materials and new energy battery materials, meeting strict fineness and purity standards for electronic raw materials. Meanwhile, they suit fine processing of paints, inks, pigments and dyes, ensuring uniform color dispersion and stable product quality. They also perform excellently in pharmaceutical, food additive and fine chemical industries, as well as mineral superfine grinding, adapting to diverse high-precision and long-term continuous production demands.
Adopting yttrium stabilization technology and high-temperature sintering process, the balls have ultra-high hardness and toughness, with far lower wear rate than glass and alumina balls. The unique toughening structure prevents breakage in high-intensity operation, extending service life significantly.
